The conundrum here is; if you put it into your will, you are effectively trusting a third party to manage your funds after death, which is completely destroying the point of managing your money in the first place. The other side is, if you don't trust a third party to handle this for you, you either need to come up with a process yourself, which is risky in itself since if you can't guarantee they'll be able to follow the instructions, i.e being too cryptic in case someone else stumbles upon it you can't guarantee they'll be able to decipher it, and gain access to the coins.
I've actually spent some time thinking about this, and one solution I came up with was a set of 3 seed-cards, stored in three different safety deposit boxes, at three different banks. The keys to the safety deposit boxes could be included in one's will. As is typical for safety deposit boxes, only the next-of-kin possessing a valid death certificate can access them. A fourth safety deposit box can be set up for the extensions, if needed.
That way, even if the relatives don't know about your bitcoin, they'll learn about it at the reading of the will, and only those relatives who inherit the safety deposit box keys will be able to access it.
I reckon they'll be a little miffed once they get started on the treasure hunt. None of it will be difficult for them, but I'll be laughing my ass off from heaven watching them scramble to find the right ones. I've been tormenting my children from the get-go, so once I'm gone they might actually enjoy my last "Dad Joke" I get to play on them.
I can only imagine how much fun it must have been coming up with the treasure hunt. Hopefully, they don't tear their hair out for years on end, because Dad hid their house money
Lol, I wish I had that much bitcoin. Unfortunately most of my wealth
IS my house. It'll be pretty easy for them to figure out where the extensions are hidden, and they'll have access to them regardless. They just won't know where to look at first, is all. It's more to provide them a game of sorts than anything else.
